Was hoping I could get some input on this. My mother (now deceased) remarried after my father's death. The man that she remarried took us all in and cared for us (to the best of his ability) when I was 12 years old. He had to deal with her always being drugged up and having out of control children to take care of-- let's just say it was a hand-ful. Well, she passed away about five years ago and got her urn- since he was her husband. Long story short, my brother and his wife stayed with him when they had no where to go. My stepfather's new girlfriend did not like them and caused fights among all of them. Well, my brother's family ended up leaving because of her and the influence she had on my step-father. He still has my mother's urn, even though my older brother wants it. My question is: I know they are fighting and disagree about the urn, but I want to invite my stepdad because he did take us in and take care of us. Any ideas to make sure they don't all fight or argue at the wedding?
